I have a Movable Type installation running the latest version of MT (currently Movable Type version 5.2.7 with: Community Pack 1.72, Professional Pack 1.53) and my client has provided us with a data export from another MT installation (we're migrating servers) that he would like imported to the new MT installation.
Unfortunately, every time we try to execute the import we receive
Your browser sent a request that this server could not understand. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
This is the ONLY part of the MT install which has this problem. I'm about to rip out the import tool and write my own processing script to do the job, since I'm not going to manually add ~750+ blog posts by hand.
Appreciate any advice that people can provide!
